Specification of Letters Patent.

Fatentecl Nov. 113, 191-4..

Application filed August 19, 1916. Serial no. mean.

To all whom it may concern:

Be it known that I, GEORGE F, MARSTON,

-a citizen of the United States, residing at Pomona, in the county of Los Angles and State of California, have invented certain new and useful Improvements in Combined Tire-Valves'and Pressure-Governors; and I do hereby declare the following to be a full,

clear, and exact description of the invention,

and similar pneumatic tire air valves and capable of enabling a compressed air pipe or air compressor to be readily connected with such tire valve and equipped with means for enabling the desired amount of pressure to be supplied to the tire and for indicating when such pressure has been reached so that the pneumatic tires will not be excessively inflated.

A further object of the invention is to provide a combined tire valve and pressure governor of this character adapted to be adjusted and, set for diflerent pressures and capable of permitting an escape of air after a tire has been inflated to the desired pressure so that such escape of air will serve as an audible signaland also as a relief,

\Vith these and other objects in view, the

invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope'of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing Figurel is a side elevation of a combined tire valve and pressure governor constructed in accordance with this invention,

Fig. 2 is a central longitudinal sectional view of the same, 1

Fig. 3 is a longitudinal sectional viewtaken at right angles to Fig. 2,

F i 4, is a transverse sectional view on the line H of Fig. 1,

Fig. 5 is a transverse sectional view on the line 55 of Fig. 2. I

Like numerals of reference designate corresponding parts in the several figures of the drawing.

In the accompanying drawing in which is illustrated. the preferred embodiment of the invention, the combined tire valve and pressure governor comprises in its construction a substantially cylindrical body 1 constructed of suitable metal or other material and having a longitudinal bore or opening 2 which is connected by a reduced portion 3 with a lower valve receiving socket a containing a rubber washer or gasket 5. The rubber washer or gasket 5 is adapted to fit around an ordinary pneumatic'tire air valve for making an air tight connection, and the said body 1 is provided at the top of the socket i with apt-ejecting portion or knob 6 adapted to engage and depress the valve stem of the air valve for openingthe" same to permit a free passage of air from a compressor or other source of supply into the valve of the tire. The longitudinal bore or opening 2 constitutes a valve chamber and the bottom wall is beveled at 7 around the upper end of, the reduced portion or exten sion 3 to form a seat for avalve 8 which is normally held closed by a coiled spring 9.

The spring 9 1S engaged by aplate or member 14 located within the upper portion of the valve chamber and provided at opposite sides with arms 15 operating in opposite slots or grooves 16 of the body 1 and arranged in the path of and adapted to-be enice W nt

' body and arranged to engage the notches for locking the sleeve against rotary movement and a catch carried by the said cap and arranged to engage the outer end of the sleeve for holding the said sleeve in engagement with the fixed projection.

5. A combined valve and pressure governor of the class described includinga body- 'havin'g a socket at one end and provided with valve stem engaging means, said body being also provided with a valve chamber communicating with the socket and having a valve seat, avalve coacting with the valve seat, a spring engaging the'valve, a washer fitted against the outer end of the spring and having arms operating in the body, a threaded valve mounted on the body and having a passage communicating with the said socket, a nut mounted on the threaded stem and arranged to engage the arms of the washers and means nut.

6. A combined valve and pressure govor operating the ernor of the class described including abody having a here or opening constituting a valve chamber and provided at its innerend. with a valve seat, a tubularstem secured in the outer end of the said bore, a valve coacting with the said valve seat, a spring engaging the valve, a asher engaging the upper end of the spring and I provided With an arm or extension; a nut mounted on the tubular stem and arranged to engage the said arm or extension for compressing the spring, a valve located. within the tubular member for preventing the escape of air from the device, said body having an air passage controlled by the valve of the tubular stem or member and extending around the valve of the body.

In-testimony whereof I afiix my signature in presence of two Witnesses.
